(Cl. 21417) The loading of centrifugal extractors, such as of extractors used in laundries, takes considerable time according to the nature of the material to be dried, whereby the utilization of the extractor is essentially lessened and high expenses for wages are entailed. For shortening the time of loading, it has been proposed to make the extractor basket removable so as to allow same to be loaded outside the machine. By providing two -removable baskets for one extractor, it is then possible to keep the extractor constantlyrunning except for the times required to remove and re-insert the basket. A serious drawback of this way of loading extractors consists in that just f that part of the extractornamely the basket- Which is most exposed to the centrifugal forces,

does not remain permanently in the extractor.

,The fact that the connection between the basket and its spindle must be loosened at each loading operation is a great danger for the service. Moreover, the removable baskets are always liable to be damaged on their transport through the shop. In order to meet with these drawbacks, it has been proposed to use in addition to amain basket which remains permanently in the extractor, another basket adapted to be loaded at the Washing machine or elsewhere and tobe placed with the material in it into the main, basket. It will, however, be clear that by the use ,of f such an additional basket the centrifugal force tobe taken up by the main basket will be im creased very considerably. Now, the present invention resides in using for the loading of extractors a portable receptacle ;which is filled with the material to be dried at any place outside the extractor, then. carried above the extractor and thereuponemptied into the extractor basket. The emptying of the receptacle may be effected either by tilting or by 40; opening bottom flaps or the like with which the formly as possible on the section of the basket,

it is contemplated according to the invention" to divide the portable receptacle into a plurality of individual chambers.

For allowing of the invention to be more readily understood, it'will now be described with ref-- erence to the accompanying drawing which shows, by way of example, a receptacle according to the invention in its position of discharge 3 above an extractor. s

basket of the extractor, preferably in one turn,

back to the washingmachine for. receiving The portable receptacle consists of a box a which is open at its top. The box is divided into two chambers b, the bottoms of which are formed by one common discharge flap or, as shown, by

In this manner the loading of the extractoris performed within as short a time as possible. After the receptacle hasbeen emptied it may immediately be carried other charge of clothes- V Itis to be understood that the portable receptacle may be given any suitable form different from that shown; it may for example be con- 'structed as a tiltablereceptacle,

centrifugal stress in the operation of the basket,

consisting. in supporting a load commensurate with the capacity of the basket above the basket for delivery into the same, with the load as supported evenly, distributed with respect tothe axial center of the load and delivering the load into the basket of the extractor while the axial centerof the load is substantially in line with the axial center of the basket.

2. The herein described method of loading the.

basket of a centrifugal extractor to distribute the material in the act of loading to avoid uneven centrifugal stress in the operation of the basket, consisting in supporting a load commensurate with the capacity of the basket above the basket for mass delivery into the same, with the load as supported evenly distributed with respect to the.

axial center of the load and delivering the load as a mass into the basket of the extractor while the axial center of the load is substantially in line with the axial center of the basket.

3. The herein described method of loading the basket of a centrifugal extractor to distribute the material in the act of loading to avoid uneven centrifugal stress in the operation of a basket, consisting in supporting the load commensurate with the capacity of the basket above the basket for mass delivery into the basket, with the load as supported divided into even, regular masses with respect to the axial center of the load and delivering the load as a mass into the basket of the extractor while the axial center of the load is substantially in line with the axial center of the basket.

4. In combination with a centrifugal extractor including a rotating basket, a loading element commensurate in size with the size of the basket and designed to be selectively positioned above the basket, with the load evenly distributed about its axial center and with this axial center in substantial alignment with the axial center of the;

basket, and means carried by the loading element and controllable at will for delivering the 7 load. therein into the basket.

5. In combination with a centrifugal extractor therein into substantially equal masses beyond and with relation to the axial center of the load ing element, and means carried by the loading element and controllable at will for delivering the load therein as a mass into the basket.
